[PATCH 0/4] perf record: Cleanups and mmap-based output

[David Ahern <dsahern@gmail.com>]

I know Jiri is working on cleanups of the output file, but had this
sitting around for a couple of weeks now. Might as well push it out
for the next baseline. The cleanups of perf-record can be taken
independently.

Ingo: I took a look at leveraging the copy_user_nocache and was not able
      to get it to work. I won't have time to come back to it for a while.
      Given that the mmap output already improves perf-trace a lot I would
      like to get the option into 3.13 and come back to the optimization
      later.

David Ahern (4):
  perf record: Refactor feature handling into a separate function
  perf record: Remove advance_output function
  perf record: Remove post_processing_offset variable
  perf record: mmap output file - v3
